The field of pathogen detection is nascent and therefore, faces a dynamic set of challenges as the field evolves. Visceral leishmaniasis (VL), or kala\u2010azar is the most severe form of leishmaniasis. Delay to the accurate diagnosis and treatment is likely to lead to fatality. The reliable, fast and sensitive detection is closely linked to safe and effective treatment of <jats:italic>Leishmania<\/jats:italic> <jats:italic>spp<\/jats:italic>. Despite several routine and old method for sensitive and specificity detection of <jats:italic>Leishmania<\/jats:italic> <jats:italic>spp<\/jats:italic>, there is highly demand for developing modern and powerfully system. In this study a novel ultra\u2010sensitive DNA\u2010based biosensor was prepared for detection of <jats:italic>Leishmania<\/jats:italic> <jats:italic>spp<\/jats:italic>. For the first time, the specific and thiolated sequences of the <jats:italic>Leishmania<\/jats:italic> spp genome (5\u2032\u2010SH\u2010[CH<jats:sub>2<\/jats:sub>]<jats:sub>6<\/jats:sub> ATCTCGTAAGCAGATCGCTGTGTCAC\u20103\u2032) were recognized by electrochemical methods. Also, selectivity of the proposed bioassay was examined by three sequences that were mismatched in 1, 2, and 3 nucleotides. The linear range (10<jats:sup>\u22126<\/jats:sup> to 10<jats:sup>\u221221<\/jats:sup> M) and limit of detection (LLOQ = 1\u2009ZM) obtained are remarkable in this study. Also, simple and cost\u2010effective construction of genosensors was another advantage of the proposal DNA\u2010based assay. The experimental results promise a fast and simple method in detection of kala\u2010azar patients with huge potential of the nanocomposite\u2010based probe for development of ideal biosensors.<\/jats:p>","DOI":"10.1002\/jmr.2839","type":"journal-article","created":{"date-parts":[[2020,4,8]],"date-time":"2020-04-08T06:15:10Z","timestamp":1586326510000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Binding
